One of my favorite Far Side cartoons depicts a student raising his hand in a classroom, “Mr. Osborne, may I be excused? My brain is full.” There have been times when I’ve felt like that student—so tired of thinking, I need to be excused. But sometimes I wonder if I’m still that exhausted student, wandering the hallways of life on a teacher’s pass. When was the last time I really stretched my mind around a new idea? I think I’ll ponder that thought today and see what new ideas come my way.

Your thoughts? What ideas have really stretched your mind?
